Not mortal, not vampire ... what is she?

Helena wants to die, but when a vampire tries to take her life she instinctively unleashes a mysterious, deadly power she never knew she had.

When Danizriel — an angel — arrives on the scene, he's puzzled to find Helena alive and the vampire dead. Intrigued, he shelters her and together they discover that she has become something neither of them expected.

Their growing attraction is soon threatened when news of Helena's unnatural abilities quickly spreads. She becomes the target of a deadly hunt by vampires and Danizriel is placed in an impossible situation when he is told he must kill her.

With overwhelming forces closing in, Helena and Danizriel face death from all directions. Who will live and who will die?
